A lady in our department bought a new computer but coudn't get it to work. I told her to bring it in, and I'd take a look at it. Next day she dropped it off, and I checked it out. All was fine. She took it home. Next day, she came in and said it still didn't work. I told her to bring the monitor in, thinking maybe it was dead. Next day, same story, no problem with the monitor. When I saw her later, I told her this and that she should take the monitor home and, if it still didn't work, bring everything in. Next day, she dropped by my office with all she had. I set it on the table, plugged everything in, flipped the CPU power switch, and she leaned in real close, wide-eyed.
"Wait!!" she exclaimed. "What was that you just did?!?!?"
